To all. whom it may comer-"11:.-

.Be it known that I, FREDERICK N. CON- NET, a citizen of the UnitedStates, residing at the city of Providence, in the county of Providenceand State of Rhode Island, have invented certain new and usefulImprovements in Indicating, Integrating, and Recording Manometers, ofwhich the following is a specification,,reference being had therein tothe accompanying drawing.

This invention relates to a combined indicating, integrating andrecording manometer, the same being adapted to automatically give thesum and total in gallons, cubic feet or other convenient units ofmeasure, of the quantity of liquids or gases passing through a givenaperture and at the same' time record the variation of the flow and alsoto. indicate at all times the quantity passing through the pipe.

provide sim 1e and effective means. for reducing the riction of movingthe integrat ing operating mechanism and recording pen so that a moreaccurate reading from both the integrator and recorder may be obtained.

In carrying out my invention I have provided an oscillatory arm or framein which the recording pen and the integrating mechanism are operativelymounted, the weight of said frame bein supported and balanced on knifeedge, w ereby the friction of carrying the pen and the integrator orcounter back and forth over the face of their respective. disks isreduced to a minimum. My deviee'is particularly adapted to regis- .terthe flow through a pipe or tube of the class commonly known as a venturitube, and said dev icemay be actuated by any desirable mechanism, butfor convenience I have shown two chambers connected to said tube onewith the u -stream or high pressure side of the tube, an thesecondcommunicab in with the throat or reduced portion of said tube.These chambers communicatewith each other, and'in each is a floatsupported on acolumn of mercury, said floats being connected throughsuitable mechanism to operate both the indicating and the integratingmechanism, and also to move a recording pen'over the face of acontinuously rotating record sheet.

' The invention is fully set forth in this specification and moreparticularly pointed out in the appended claims.

Fi 5-- isan enlarged side elevationillustrating the means for operating the register, also the adjustableweight or counterbalancing the same and regulatin the pressure of thefriction wheel on the driving disk.

Fig. 7 is a modification showing another arrangement wherebyfloats may actuate the cam through a set of differentlal gearing.

' Referring to the drawings, at '1 is the base or frame on which, issupported a pair of cylinders 2 and 3, cylinder 2 being set somewhathigher than cylinder 3. At the lower end of each of these cylinders is apipe 4 through which theftwo cylinders are connected together. The upperend of cylinder 2 is provlded with a short neck 5 communieating with thecircular opening 6' and a stand-pipe 7 extends upward from said openingin line with its neck 5, making the whole cylinder selfcontained andwatertight. The cylinder 3 is provided with a long neck 8 communicatingwith a circular chamber 9, corresponding to and in line horizontally.with the circular chamber 6, and a stand-pipe 10'extends upward fromthe opening 11 in line with its neck 8, making this cylinder also tightagainst a pressure of water. At 11 is a horizontal shaft extending fromthe circular chamber 9 through the circular chamber 6 and out throughthe bearing 12, the actuating cam 13 being mounted on this end. .Thisshaft is provided with a suitable bearin 14 between the two chambers anda stu g box 15 as it extends from the circular chamber 6 out into thefront casing. A gear 16 located in this chamber is mounted on and fixedto this shaft, and a similar gear 17 located in chamber 9 is alsomounted on and fixed to this same shaft. At-18 and 19 are two floatsadapted to rest on and be moved vertically by the change in the levelsof the mercury in both of the cylinders.

To the upper end of float 18 is connected a long rack 20 adapted toengage one side of the gear 16, whi e to the float 19 is also connected9. similar rack 21 adapted to engage the opposite side of the gear 17.When either of the floats is way up the rack extends into its stand-pipeand when the float is way down the bottom of the same rests upon thelower end of its cylinder.

At 22 is a disk or driver mounted on the shaft 23 to be'rotatedcontinuously by clock work or other con'venient mechanism, not

. shown.

24 designates a frame or arm, the upper portion of which is formed insubstantially per portion of this frame and is supported" in bearings303O on either side thereof, and on this shaft the counter or register31 is loosely suspended. On the back of this counter are fixed thebrackets 3232 from which the horizontal shaft 33 is rotatably supportedon the adjustable, bearing screws 32*, and to this shaft is fixed thefriction wheel 34. The edge of this wheel is adapted to rest againsttheface of the driving disk 22 and drive the counter through the gears 35and 36.

As the shaft 29 on which the counter is hung passes through the same ata point in the rear of its center of gravity, the lower portion ofsaidcounter has a tendency to hang backward or'rearward out of a verticalline and carry the friction wheel 34 against the face of the drivingdisk 22. In order toregulate the pressure of this friction wheel againstthe face of said "driving disk I have provided an arm 37 fixed to theface of the register at 38 and extending upward and rearward, and onthis arm is mounted a weight 39 adapted to be adjusted along the same soas to counterbalance to some extent the-rearwardly hanging tendency ofsaid register and so regulate the pressure of the friction wheel againstthe face of the driving disk. The front face of the machine is cut awayor slotted at31 to allow the counter to be visible as it is moved fromone end of its stroke to the,

other. Above this counter is a record sheet disk 40 the same beingmounted on a shaft- 41 to be continuously rotated-by clock works orother convenient mechanism, not shown. On this disk'is mounted a recordsheet 42, which may be ruled or arranged in any convenient manner. Arecording pen or pencil .tion. .hand 49 is mounted on the end of theshaft 43 is supported on an upwardly extending arm 44,; which latter isconnected at 45 to one side of the frame 24, said pen being thus adaptedto be moved over and to mark upon the face of the record sheet as saidframe is oscillated or moved in the manner hereinafter described. Inorder to control the movement of this oscillatory frame a contact roll46 is arranged to project from the face of said frame and is caused torest against the edge 47 of the actuating cam 13 by means of thecounterbalancing weight 48. The working edge of this cam is made in ashape necessary to control the movement of said frame in a givenproportion to the amount of water passing through the tube, so that itwill be properly positioned to cause a proper record to be made on thechart and also to properly actuate the register. In some cases it isalso advisable to provide an indicator which will show at a glance thenumber of gallons passing through the meter at the time of observa- Inorder to accomplish this result a 11, which is caused to move over theface of a graduated disk 50, see Fig. 1, so that the position of thehand on the same will ac; curately indicate the number of gallonspassing through at the time of the reading.

The operation of the device may be more fully described. as follows: Theliquids or gases flow through the tube 51 in the direction of the arrow.The up-stream side of the tube is connected at 52 by means of pipe 53 tothe cylinder 3, while the throat is connected at 54 by the pipe 55 tothe cylinder 2. When there is no flow through the tube the pressure atall points of the tube is, of

course, equal and the floats in both cylinders are at the same height.As soon as the flow begins the pressure in the throat is decreased andbecomes less than that at the point 52, therefore the mercury in chamber3 is forced downward by the excess of pressure on .this side, raisingthe mercury and float in the opposite chamber a corresponding amount. Asthese floats move one up and one down they act with corresponding forcethrough their respective racks and gears on opposite sides of the shaft11 to rotate the actuating cam 13 in proportion to their movement. Whenthere is no flow through the tube the indicating hand 49 is at zero, thecounter operating friction wheel .34 is at the center of the rotatingdriving disk 22 where it will not turn, and the marking pen 43 is at thezero point on its record sheet. As soon as the flow begins the floatschange their relative levels rotating the 'cam in the direction of thearrow thereby allowing the frame to be moved to the right by means ofthe counterbalance weight 48, carrying the contact wheel from the centerof the diskalong the face of the speed in proportion to its distancefrom constant or varying, is clearly and accurately recorded on therecord sheet for a predetermined period. These sheets when operated uponby the mechanism described should be removed and replaced by a; freshoneevery twenty-four hours. The integrating mechanism keeps on adding fromday to day, and shows at all times the total amount used, while theindicating hand shows at once the amount that is passing through at thetime of observation.

By the use of my improved construction the friction of moving theintegrating mechanism' is reduced to the minimum, thus ren-. dering itpossible for the device, owing to the-lack of friction, to accuratelyindicate, register and record the amount of flow.

Fig. 7 illustrates a modification by which the cam 13 may be actuated,whereby the floats 60 and 61 are moved in their respective cylinders 62and63 by the difference in a the pressures in the main pipe, said floatsbeing arranged to operate said cam throu h the cords. 64 and 65 and thedifferential I gearing shown.

I do not restrict myself to the constructions shown of using floats incylinders for .the purpose of operating the mechanism, as

1 any suitable or convenient means may be employed for controlling themovement of the counter, the recording pen andthe indicating handinproportion to the velocity flow through the pipe, without departing Ifrom the spirit and scope of my invention.
